OSRS Cannon Money Making Guide for 2025

In Old School RuneScape (OSRS), the Dwarf Multicannon is a game-changer for players looking to combine combat training with profit. While it’s primarily known for boosting Ranged and Slayer XP, savvy players can leverage the cannon for money-making opportunities. This guide dives into the best strategies to make gold using the cannon, from crafting cannonballs to choosing profitable combat spots. Whether you’re a mid-level player or a seasoned veteran, you’ll find actionable tips to maximize your GP per hour.

The Dwarf Multicannon is a members-only item unlocked after completing the Dwarf Cannon quest. It’s a powerful tool that automatically attacks monsters in a multi-combat area, making it ideal for training and looting. However, using it for profit requires careful planning due to the cost of cannonballs and maintenance.

Requirements to Get Started

Before you can start making money with the cannon, you need to meet these prerequisites:

• Complete the Dwarf Cannon Quest: No skill requirements, just a short quest north of Falador.
• Purchase the Cannon: Costs around 750k GP from Nulodion or the Grand Exchange.
• Ammo Mould: Obtained during the quest for smithing cannonballs.
• Optional: Sleeping Giants quest for the double ammo mould to boost cannonball production.

Cost of Cannonballs

Cannonballs are the fuel for your cannon, and their cost can eat into profits if not managed. As of 2025, one steel bar (approx. 680-700 GP) produces four cannonballs (worth around 1,150-1,200 GP total). The profit margin depends on Grand Exchange prices, so always check live rates before investing.

Smithing Cannonballs for Profit

One of the most reliable ways to make money with the cannon is by smithing cannonballs. This method is AFK, low-effort, and profitable due to consistent demand for cannonballs in OSRS.

How to Smith Cannonballs

Here’s the step-by-step process:

1. Gather Materials: Buy steel bars from the Grand Exchange or smelt them yourself (one iron ore + two coal).
2. Equip the Ammo Mould: Obtained from the Dwarf Cannon quest.
3. Head to a Furnace: Edgeville is ideal for its proximity to a bank.
4. Smelt: Use steel bars on the furnace to produce four cannonballs per bar.

Profit and Efficiency

Without the double ammo mould, you can produce 2,160–2,400 cannonballs per hour, yielding a profit of 250k–280k GP. With the double ammo mould (unlocked via Sleeping Giants), production doubles to 4,320–4,800 cannonballs, boosting profits to 500k–560k GP per hour. The trade-off is more frequent banking, but the GP gain is worth it.

Method	Cannonballs/Hour	Profit/Hour (GP)	Requirements
Standard Ammo Mould	2,160–2,400	250k–280k	35 Smithing, Dwarf Cannon
Double Ammo Mould	4,320–4,800	500k–560k	35 Smithing, Sleeping Giants

Tips for Maximizing Smithing Profits

• Use Edgeville Furnace: It’s the closest to a bank, minimizing travel time.
• Check GE Prices: Ensure steel bars are cheaper than cannonballs for optimal margins.
• AFK with Media: Since smithing is repetitive, play music or watch a show to stay engaged.

Using the Cannon in Combat for Profit

While smithing cannonballs is a safe bet, using the cannon in combat can yield profits through loot drops, especially in specific locations. The key is to target monsters with valuable drops that offset cannonball costs.

Best Cannon Spots for Money

Here are three low-competition spots where you can make money while cannoning:

Scabarites (Sophanem Dungeon)

Located in the dungeon from the Contact! quest, Scabarites drop stackable items like noted adamantite ore, blood runes, and rune items. With a cannon, you can expect 300k–500k GP per hour after cannonball costs, plus decent Ranged XP.

• Requirements: Contact! quest, 60+ Ranged, light source.
• Gear: High Ranged attack gear, prayer potions for protection.
• Profit Tip: High Alchemy runes can turn junk drops into extra GP.

Ice Trolls (Fremennik Isles)

Ice Trolls on Jatizso or Neitiznot offer break-even or slight profits due to their drops like rune items and noted herbs. They’re great for players with Fremennik Trials completed, yielding 200k–300k GP per hour.

• Requirements: Fremennik Trials, 60+ Ranged.
• Gear: Melee or Ranged setup with food for sustainability.
• Profit Tip: Prioritize worlds with fewer players to maximize loot.

Cave Horrors (Mos Le’Harmless)

Cave Horrors drop black masks and herbs, which can cover cannonball costs and generate 200k–400k GP per hour. The single-combat area lowers XP but boosts loot potential.

• Requirements: Cabin Fever, 58 Slayer, witchwood icon.
• Gear: Slayer helm or black mask, Ranged gear.
• Profit Tip: Bring a blowpipe for faster kills alongside the cannon.

Challenges of Combat Cannoning

Combat cannoning for profit isn’t always straightforward. Cannonballs cost around 280–300 GP each, and you’ll use hundreds per hour. To break even, your loot must consistently outvalue this expense. Additionally, some spots like green dragons are risky due to PKers, so stick to safer areas unless you’re prepared.

Flipping Cannon Parts for Profit

Another creative way to make money with the cannon is by flipping cannon parts or sets on the Grand Exchange. This method doesn’t involve combat or smithing but leverages market trends.

How to Flip Cannon Parts

After completing the Dwarf Cannon quest, you can buy cannon pieces (base, stand, barrels, furnace) from Nulodion for 200k each or a full set for 750k. Here’s the strategy:

1. Buy Low: Purchase cannon sets or parts from the GE when prices dip below Nulodion’s rate.
2. Sell High: List them back on the GE when margins are favorable (e.g., 800k–1M for a set).
3. Monitor Margins: Use tools like GE Tracker to track price trends.

Potential Profits

Flipping can yield 50k–250k GP per set, with top earners hitting 3M per hour during price spikes. However, this method requires starting capital (1M+) and market knowledge to avoid losses.

Risks and Tips

• Risk: GE prices fluctuate, and you could lose GP if margins shrink.
• Tip: Start with one or two sets to test the waters before scaling up.
• Tip: Avoid flipping during low-demand periods (e.g., major game updates).

Tips to Maximize Cannon Money Making

Whether you’re smithing, fighting, or flipping, these tips will help you get the most out of your cannon:

• Track Expenses: Always calculate cannonball costs versus loot or sales to ensure profitability.
• Upgrade to Double Mould: If smithing, prioritize Sleeping Giants for double ammo mould—it’s a game-changer.
• Use Safe Spots: In combat, position your cannon to minimize damage taken, saving on food and potions.
• Combine with Slayer: Cannon Slayer tasks in multi-combat areas to earn XP and loot simultaneously.
• Stay Updated: Follow OSRS price trackers like GE Tracker to catch market shifts.

Final Thoughts: Making money with the OSRS cannon is all about balancing costs and rewards. Smithing cannonballs offers steady, AFK profits, while combat cannoning can yield higher GP with the right setup. Flipping parts is a high-risk, high-reward option for market-savvy players. Experiment with these methods to find what fits your playstyle, and always keep an eye on the Grand Exchange for the best deals. Happy grinding!
